"This invention relates toduplicating'machines operating onthehectographprinciple and wherein Aa gelatin band is stretched across `the bed ofthemachine .to Withdrawn froma roll atene end of the `machine and. woundupon-a 4roll at theother end of the machinevvherebyzaiform to beAduplicated may be transferredonto the portion ofthe band stretched.across the `bed to' provide a matrix from which impressions may be madel onto sheets applied thereto.

VVHe'ctograph duplicating machines usually embody a carriage mounted on...rollers traveling `on .trackvvays kextending parallel with .the bedof the machine whereby the carriage may be reciprocable over the portionofthe gelatin band stretched across the bed. When afform isto betransferred onto the band to provide amatrix it is customary to use thecarriage to apply the original sheet carrying the form to the band `andtherefore when the sheets to receive the impressions are subsequentlyapplied Ito the band by the :carriage in the same manner as that inwhich' thefform was applied. the 4registration ofthe vform on .theimpression receiving sheets yWill correspend tothe registration oftheform on `the original sheet. It `is therefore necessary that thecarri-age `repetitiously reciprocate over the-portion of thegelatin bandprovid- .ing the matriXrin a uniform manner .sothat proper registrationof the impression receiving sheets relative to the l'matrix Will be.as'- sured lTo assu-re such uniform reciprocation, it is tcommontoprovide a guide fr od.

-at the side of the machine and to so connect the carriage to-this guiderod that the :carringe be properly'g-.uided thereby. A high degree 'of`accinacyis required in :the guiding of the carriage and beca-use ofthisit isnecessary that the guide rod be accurate- 1y positioned. Moreownf,lboth the :guide rod and the trackways are :carried 'by the frame :and'as the carriage travels on both the track- 'Ways 'and the guide rod it4is necessary that theguide rod `,be positioned accurately relative tothe trackwaysito avoid binding during reciprocat-i-on of the carriage.'In the `past it has beenvery diiicult to'prevent'thisbinding Vwhere thecarriage isfso connected tothe tracliways that it" isfheldn `againstvertical' movementwith respect theretoand the salient objecty 'of myinvention is provide afdiipli-` cating lmachine y'wherein trackways for.snp:

porting thecarriage'and a guide rod will he i provided andfto so mount:the carriage for inovelnentjon the'trackvvays` and t0 so conf' nect thecarriage totheguiderod that bindlng' of the carriage lduringreciproc'ation thereof will be prevented. V l

Referring to the drawings wherein I haveillustrated a selectedembodiment of my invention, 10 indicates the bed of a hectographduplicating machine supported between side members 11 and 12 mounted atthe upper end of the side wall members 13 and 14 of a suitable frame orlthe like. c A gelatin band B is directed across the bed 10 from a supplyroll 15, at vthe rear end of the bed, to a take-up roll 16,'at the frontend of the bed, and suitable means to be described hereinafter `areprovidedfor winding the band from either 0f these rolls onto the other.A carriage C is provided which includes side frame members 17 and'18. Inthe side frame member 17 are studs 19 on which wheels 20 are rotatablymountedand these wheels travel along the Y upper surface of thehorizontal flange 21 of the side member 11. Y yStuds 22 are also mountedin the side frame member 17 and carry wheels 23 which travel .on theunderside of the horizontal flange 21. As best illustrated in Fig. 1the'wheels 20 are provided adjacent the ends of the side frame member 17and the wheels 23 are Ymounted in substantially Avertical alignment withthe wheels 20.- In the Side frame member 18 adjacent the ends thereofare studs 24 (Fig. 3) onwwhich wheels 25 are rotatably mounted, whichwheels are adapted .toy travel on the upper side of the horizontalflange 26 of the side member 12. Thus the carriage is supportedfb'y thewheels thereon for movement overthe horizontal flanges which providestrackways and support the carriage during movement thereof over theportion of the gelatin band disposed lon the bed 10. The carriage Cincludes a paper guide G over which a sheet may be passed to be insertedbetween `the clamping roller 27 and the platen roller P both of whichare mounted in the carriage C. The platen roller P is mounted in arockable frame 28 on which there is a handle 29. By grasping-the handle29 the platen roller may be moved into a position abovev and away fromthe clamping roller 27 to permit a sheet to be passed between theserollers. vrAfter the sheet' has been passed between the rollers theplaten roller P is caused to move past theV center i of the clampingroller 27 into a lowered position wherein it is forced toward the bandand the sheet is tightly held against the band as well as being securelyclamped be tween the platen roller andthe clamping roller. Since theplaten roller is, in eifect,

clamped against the band it will be rotated as the carriage moves overthe portion of and the impression lreceiving sheets are laid upon thegelatin band-by Vthe platen roller P in the manner above described andsince both the original formand the impression receiving sheets areapplied to the bandB by the platen roller, it is manifest that 'proper'registration of the impression on the impressionreceiving sheets willresult provided the carriage repetitiously operates in a uniform mannerupon successiveoperations.V To assure such operation it is necessarythatthe carriage be held against transversevmovement with respectl to theband otherthan the reciprocatory movement thereover. To

accomplish this a guide rod 30 is mounted ben low the horizontal yflange26, and is, therefore, below the plane of the bed 10, and this guide rodis suitably supported from the side member l2. Collars 31 are mountedronthe guide rod 30 and have peripheral grooves 32 therein. A strip 33 issecured in the vside` frame member` 18 below the horizontal flange 26 bybolts 34 or the like and has the main extent thereof extendedsubstantially parallel with the side frame member.

provided adjacent each 'endA 'of ythe sidey frame member 18. .Thecollars 31 are slidable on the rod- 30 and inasmuchjas these collars arespaced apart an effective guide is provided which prevents transversemovement of the carriage with respect tothe gelatin band other than thereciprocatory move-` ment thereof and in this manner uniformreciprocation ofthe carriage upon successive operations thereof isinsured to thereby 1nsure proper registration of the form on the if'sheets. It should be noted that rollers are provided on both sides oftheii'ange or trackway 21 while rollers are provided on but one side ofthe flange or trackway 26 and that the guide rod is mounted below thistrackway y `'Iheen'ds of zg, 'the strip 33 extend at right angles tothehtightly across the bed toy insure'that clear impression receivingsheets'when so desired. Inasmuch as the gelatinbandmust be drawn cutimpressions be made therefrom, a brake device, operated r.bythe handle58, may be provided and' one such brake-devicesuitable `for use inY thismachineis disclosed in m copending application nSerial No. filedSeptember 11, 1931.

From the foregoing description it is manifestthat I have provided aduplicating ma`- chine wherein the carriage will uniformly reciprocateover the 'bed ofl the machine to linsure proper applyingof the sheets tothe `matrix so that properly oriented impressions y at opposite ends ofthe bed which facilitates said bed,

rproper positioning of the matrix.
